As you've undoubtedly heard, AMD recently launched its Radeon HD 5000 GPUs
-- all of which have been 5700
or 5800 series
cards. Yesterday, the company released a new Open CL-compliant driver for present Radeon HD 4000 and 5000 video cards that Fudzilla says
reveals an undisclosed Radeon HD 5000 offering.
The Tech Report
looked at the driver's INF files, and sure enough, in addition to the three Radeon HD 5700 and two 5800 listings are two 5900 entries. The site suggests that the three 5700 entries account for the 5770, as well as 512MB and 1GB versions of the 5750, while the two 5800 listings are almost surely the 5850 and 5870 cards.
It seems probable that AMD may be preparing a temporary counter to Nvidia's Fermi-based GPUs, but what exactly does the company have in store for the Radeon HD 5900 series?
